| dc.description.abstract | Hutan dataran rendah perlu diteliti struktur dan komposisinya karena
memiliki keanekaragaman hayati yang tinggi. Analisis vegetasi ditujukan untuk
mengetahui komposisi jenis dan struktur vegetasi hutan dataran rendah Suaka
Margasatwa Pulau Rambut. Analisis vegetasi dilakukan dengan metode jalur dan
garis berpetak dengan luasan yang diamati sebesar 20.000 m2
dengan jumlah jalur
pengamatan 10 jalur dengan ukuran 20 m x100 m. Data vegetasi yang diperoleh
diolah untuk mendapatkan Indeks Nilai Penting (INP), Indeks Keanekaragaman
Jenis Tumbuhan, Indeks Dominansi Jenis, Indeks Kekayaan Jenis dan Indeks
Kemerataan Jenis. Pengambilan data abiotik seperti intensitas cahaya, ketinggian,
kelerengan, suhu basah dan kering, kelembaban relatif, pH tanah, Kapasitas Tukar
Kation tanah, dan tekstur tanah. Tumbuhan penyusun di lokasi penelitian terdapat
15 jenis. Kedoya mendominasi pada tingkat pohon, mengkudu mendominasi pada
tingkat tiang, jeruk kingkit mendominasi pada tingkat pancang, dan kedoya
medominasi pada tingkat semai. Nilai kerapatan tertinggi terdapat pada tingkat
pertumbuhan semai sebesar 900500 individu ha-1
sehingga menghasilkan kurva “J”
terbalik baik dalam struktur vertikal maupun horizontal. | id |
| dc.description.sponsorship | Lowland forest needs to be studied for its structure and composition because
it has high biodiversity. Vegetation analysis aims to determine the species
composition and structures of lowland forest vegetation in Pulau Rambut Wildlife
Reserve. Vegetation analysis was carried out by the stripes and plotted lines with
an observed area of 20,000 m2 with several ten lines of observation with an area
of 20x100 m. The vegetation data obtained were processed to obtain the
Importance Value Index (INP), the Plant Species Diversity Index, the Species
Dominance Index, the Species Richness Index and the Species Evenness Index.
Retrieval of abiotic data such as light intensity, altitude, slope, wet and dry
temperature, relative humidity, soil pH, soil cation exchange capacity, and soil
texture. There are 15 types of plants in the research location. Kedoya dominates at
the tree level, mengkudu dominates at the pole level, kingkit dominates at the
sapling level, and kedoya dominates at the seedling level. The highest density
value is found at the seedling growth rate of 900 500 individuals ha-1 resulting in
an inverted “J” curve in both vertical and horizontal structures. | id |
